One way to solve the quadratic equation x2 = 9 is to subtract 9 from both sides to get one side equal to 0: x2 – 9 = 0. The expression on the left can be factored:
(x + 3)(x – 3) = 0. Using the zero factor property, you know this means x + 3 = 0 or x – 3 = 0, so x = −3 or 3

Answers
Answer:
3 1/3 cups total
Step-by-step explanation:
Add together 2 1/8 cups and 1 5/24 cups. The LCD here is 24, and so we rewrite 2 1/8 cups as 2 3/24 cups.
Adding 2 3/24 cups and 1 5/24 cups, we get 3 8/24 cups,

Johnny and his father go fishing at 5:00 AM. After motoring 6 km upstream, Johnny writes a letter to his friend, puts the letter in a bottle, and drops it into the river. The bottle floats in the current and reaches at 7:40 AM the point where Johnny and his father began their trip. If the speed of the boat in still water is 9 km/h, what is the speed of the river current?
Answers
Answer:9/2 km per hour
Step-by-step explanation:
equation,
6/9-x + 6/x=8/3
Upstream is flowing of the boat in the opposite direction of the stream. The speed of the river current is 4.5 km per hour.
Given-Johnny and his father go fishing at 5:00 AM.
Total traveled by the Johnny and his father in upstream is 6 km.
The speed of the boat is 9 km/h.
What is upstream?
Upstream is flowing of the boat in the opposite direction of the stream.
Let x be the speed of the river current.
Time taken by the Johnny and his father to travel 6 km in upstream is ,
[tex]=\dfrac{6}{9-x}[/tex]
The time taken by the bottle to floats in the current river is,
[tex]=\dfrac{6}{x}[/tex]
As Johnny and his father start from 5:00 AM and the bottle reached to the point where Johnny and his father began their trip at 7:40 AM. Thus the total time is,
[tex]=7:40-5:00[/tex]
[tex]=2:40[/tex]
In hours,
[tex]=2\dfrac{40}{60}[/tex]
[tex]=\dfrac{8}{3}[/tex]
As the total time is equal to the sum of the Time taken by the Johnny and his father to travel 6 km in upstream and The time taken by the bottle to floats in the current river. Thus,
[tex]\dfrac{6}{9-x}+\dfrac{6}{x}=\dfrac{8}{3}[/tex]
[tex]\dfrac{6x+54-6x}{9x-x^2}= \dfrac{8}{3}[/tex]
[tex]\dfrac{27}{9x-x^2}= \dfrac{4}{3}[/tex]
[tex]x^2-9x+\dfrac{81}{4}=0[/tex]
On solving the above quadratic equation we get the positive value of the x is 4.5.
Thus the speed of the river current is 4.5 km per hour.

If the sequence 4, 8, 12, 16 continues, what will be the 7th
term?
Answers
Answer:
28
Step-by-step explanation:
In order to find the seventh term in this arithmetic function, you need to find its function; in order to do this, you must first identify the common difference by finding the difference between two consecutive terms:
16 - 12 = 4; the common difference is 4
Now, you need to find the 0th term, which is the 1st term minus the common difference:
4 - 4 = 0
At this point, you can write out the function (where f(n) = [0th term] + [common difference]n:
f(n) = 4n
Finally, you can plug 7 into this function:
f(n) = 4(7)
f(n) = 28, so the 7th term is 28

It would take 6 hours.
An equation for that could be: 50x = 300 (X is how long it would take)

Which of these statements is true? Sin 18° = cos 72°, sin 55° = cos 55°, sing 72° = cos 18°c both a and c
Answers
Answer:
Sin 18° = cos 72° and sin 72° = cos 18°
Step-by-step explanation:
According to trigonometry identity;
sin Ф = cos(90 - Ф)
for Sin 18° = cos 72
Ф = 18°
Substitute into the expression
sin Ф = cos(90 - Ф)
sin 18 = cos(90 - 18)
Sin 18 = cos 72
Hence the statement id true
For sin 72° = cos 18
Ф = 72°
Substitute into the expression
sin Ф = cos(90 - Ф)
sin 72 = cos(90 - 72)
Sin 72 = cos 18
Hence this statement too is correct
The two correct statements are Sin 18° = cos 72° and sin 72° = cos 18°

A square has an area of 313.29m2.
Work out the perimeter of the square.
Answers
The perimeter of the square is 70.8 meters.
To find the perimeter of a square, we need to know either the length of one side or the area of the square. In this case, we are given the area of the square as 313.29 m².
The formula for the area of a square is:
Area = side length²
We can rearrange this formula to solve for the side length:
Side length = √Area
Substituting the given area into the formula, we have:
Side length = √313.29 m²
Calculating the square root of 313.29, we find that the side length of the square is approximately 17.7 meters (rounded to one decimal place).
Since a square has four equal sides, the perimeter is simply four times the side length:
Perimeter = 4 * 17.7 m = 70.8 meters
As a result, the square's circumference is 70.8 metres.

22 The distance around a meteor crater is 9,031 ft. Find the diameter of the crater. Use 22/7
(Type an integer or decimal rounded to the nearest tenth as needed.)
Answers
Answer:
d = 2873.5 feet
Step-by-step explanation:
Given that,
The distance around a meteor crater is 9,031 ft.
We need to find the diameter of the crater. The circumference of a circle is given by :
[tex]C=2\pi r[/tex]
Where
r is the radius of the circle
So,
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{9031}{2\times \dfrac{22}{7}}\\\\r=1436.75\ ft[/tex]
Since,
Diameter, d = 2r
[tex]d=2\times 1436.75\\\\d=2873.5\ ft[/tex]
So, the diameter of the crater is equal to 2873.5 feet.
Find the value of the variable(s). If your answer is not an integer, leave it in simplest radical form.
